PC393
LOW POWER DUAL COMPARATORS
DESCRIPTION
The
µ
PC393 is a dual comparator which is designed
to operate from a single power supply over a wide range
of voltage. Operation from split power supplies is also
possible and the power supply current drain is very low.
Further advantage, the input common-mode voltage in-
cludes ground, even though operated from a single power
supply voltage.
FEATURES
• Common-mode input voltage range includes V
–
• Wide supply voltage range

Notes 1.
Reverse connection of supply voltage can cause destruction.
2.
The input voltage should be allowed to input without damage or destruction independent of the
magnitude of V
+
. Either input signal should not be allowed to go negative by more than 0.3 V. The normal
operation will establish when any input is within the Common Mode Input Voltage Range of electrical
characteristics.
3.
This specification is the voltage which should be allowed to supply to the output terminal from external
without damage or destruction independent of the magnitude of V
+
. Even during the transition period
of supply voltage, power on/off etc., this specification should be kept.
4.
Thermal derating factor is –5.0 mW/°C when operating ambient temperature is higher than 55
°C.
5.
Thermal derating factor is –4.4 mW/°C when operating ambient temperature is higher than 25
°C.
6.
Short circuits from the output to V
+
can cause destruction. Pay careful attention to the total power
dissipation not to exceed the absolute maximum ratings, Note 4 and Note 5.
